Objective:

To describe the phases of a Pragmatic Clinical Trial (PCT) as a methodology for the transformation of health policies.

Development:

The Pragmatic Clinical Trial (PCT) not only considers clinical scenarios, it involves visits in real contexts such as communities and homes. It also implies administrative manage-ment, cultural feasibility, socioeconomic study and political proposal to improve health services. The phases of a PCT are: (1) Description of the phenomenon, (2) Feasibility study, (3) Implementation, (4) Clinical utility, (5) Public policy and (6) Evaluation.

Final considerations:

The contribution of nursing interventions to socie-ty (derived from scientific evidence) could be considered by political actors, who can assess the external validity of a PCT, because the data is translatable and usable in real life, at a lower cost and with less expensive interventions.
